In the provided materials the name Leucosia appears as a Latinized/Anglicized label applied in several different contexts rather than as a fully attested ancient origin story. Within the mythic strand contained in the sources, Leucosia is listed as a possible name for one of the Sirens of Greek mythology; however, the supplied corpus does not include an extant ancient narrative or detailed provenance specific to a Siren called Leucosia. Separately, modern scientific usage has applied the same name to a genus of crabs in the family Leucosiidae, and contemporary fiction and media have reused the name for characters and events (e.g., a persona in Ready Player One, an entity in Sonic-related fiction, and a named cyclone). The sources therefore treat Leucosia as a reused classical-sounding name attached to several distinct referents rather than providing a single, attested mythic origin tale for a unique deity or spirit.
For the Siren-associated sense, the sources give no direct physical description of Leucosia herself; the supplied mythic material emphasizes Sirens' vocal power rather than a consistent bodily depiction, and no species-specific morphology for Leucosia is recorded in the provided texts. For the biological genus Leucosia (crab), the family Leucosiidae is described in field notes as composed of small, pebble-like crabs (for related pebble crabs: "Body width 1–2 cm. Body smooth somewhat rhomboid, indeed resembling [a pebble]") and Leucosia is listed as a genus within that family; the excerpts do not supply species-level morphological detail.
When treated as one of the Sirens in the supplied sources, Leucosia is credited by association with the standard Siren faculty: an ability to sing in a hypnotic fashion, projecting voices across distances to mesmerize listeners and compel them to follow commands, even to their deaths. The taxonomic sense as a crab genus carries no supernatural abilities in the sources; behavioral notes for Leucosiidae indicate a life habit of burying in sand in silty or sandy shore areas near seagrasses and resembling pebbles. Modern fictional uses sometimes ascribe other capacities to characters named Leucosia (for example, an implied psychical/collective-mind role in a Sonic-related fictional entry), but those traits are specific to those contemporary works and are not part of the classical Siren attribution in the provided materials.

Les Lavandières
Three supernatural entities in Celtic tradition associated with death and mortality. (Note: - Power tier: Minor Spirit (not Greater) as their abilities seem limited in scope. - Origin story: Mention "possibly" is not necessary; the text directly states a connection to the triple goddess, but)
Lesbian vampire
A literary and cinematic trope that fuses traditional vampire motifs with eroticized female same‑sex desire. Originating in 19th‑century Gothic fiction and developed through 20th‑century cinema, the figure functions narratively to explore, sensationalize, or critique sapphic desire and female sexual transgression.
Leshy
A tutelary forest being in Slavic folklore; an embodied, territorial power of the woods that can protect, mislead, or punish humans depending on their behaviour toward the forest. Highly variable in form and described across many regional variants and names.
Lete
Lete is not attested in the provided sources as a supernatural being. The attested uses of the form 'Lete' are lexical and onomastic: a Basque toponym and surname, an ancient city (Lete in Mygdonia), a modern village in Nepal, an entry-word in the constructed language Toki Pona meaning 'cold' (with an associated glyph), an esoteric programming language (esolang) called Lete, an ICAO airport code (LETE for Morante Airfield), and a proper name applied to an exoplanet. No sources in the consulted corpus describe Lete as a spirit, demon, deity, or monster.
Lethus
Lethus is not attested as a single traditional supernatural being in the supplied sources; the lexical form appears in multiple unrelated contexts: as a Greek mythic personal name (father of Pylaeus), as a taxonomic label in entomology, as modern personal/user names, and as a single modern fan-made fictional monster (the "Lethus Dragon" on a D&D wiki). No coherent folkloric ontology, rituals, or traditional powers are documented for an entity called Lethus.
Leto
Leto (Ancient Greek: Λητώ / Λατώ; Latin: Latona) is an ancient Greek goddess best known as the mother of the Olympian twins Apollo and Artemis. She functions in myth and cult as a kourotrophic (mother‑or nurse‑goddess) figure with important sanctuaries at Delos and the Letoon in Lycia, and appears in narratives that emphasize both mildness and the capacity to call down retribution when insulted.
Levan (unattested forest spirit — proposed)
No supplied sources attestate a supernatural being named Levan in Georgian tradition. The name Levan appears in the provided materials only as a Georgian masculine given name and in various toponyms and archival name references; there is no folkloric description, origin story, or ritual material relating to a forest spirit by this name in the supplied sources.
Leviathan
A giant sea serpent in Jewish mythology, embodying chaos and serving as a metaphor for a powerful enemy. (Note: - Power tier should be Ancient (Leviathan's abilities are often described as deity-level, such as threatening the damned after their lives are over and being annihilated) - Appearance is not mentioned)
Leyak
A flying head with entrails, targeting pregnant women and newborn children in Balinese folklore. (Note: - Power tier: Primordial (given the cosmic-level abilities of targeting pregnant women and newborn children) - Abilities: The draft only mentions sucking blood, but source material mentions abducting )
Leđan (Slavic tradition)
An ancient and magical city from Croatian mythology and folklore. (Note: 1. Power tier: downgrade to Greater (since Leđan is described as an "ancient" city, but its magical nature and lack of explicit abilities suggest it may be less powerful than Ancient). 2. Appearance: )
Lha
Lha is a Tibetan term used in Buddhist and related Himalayan contexts to denote local or regional deities and divine presences that have been incorporated into the ritual and popular religion of Tibet and neighbouring areas. The category overlaps with indigenous spirits and classical Buddhist beings (devas, yakshas) and functions within ritual life as objects of veneration, territorial sacralization, and protective or beneficent cult practice.
Libat
Libat is the Mandaic name for the planet Venus and one of the Seven (šuba) planetary beings who form part of Ruha's entourage in the Mandaean World of Darkness. Treated both as the astronomical Venus and as an agentive supernatural being, Libat is associated with love and reproduction yet is often framed negatively as a demonic power (daiuia) and sometimes identified with Ruha or her epithets such as Amamit and ʿstira/Estira.
